由於製程技術快速的演進，使得積體電路在單位面積下之電晶體數成倍數增加，在單一晶片中可放入更多電路，也讓產品能朝向微型化之設計。除此之外，無線網路規格的持續發展，讓網路不再是電腦系統所獨有，近年來的發展出現ZigBee/IEEE 802.15.4，即感測器擁有網路的功能，形成感測器網路，使得感測器變的更有智慧。在不久之後，積體電路設計不再只強調前端電路與加速硬體之設計，而是在整合與功\能性方面，持續朝向系統單晶片之發展。
本論文第一主題在於IEEE 802.15.4網路之原型實作，以及硬體設計。原型實作是實現一個高移植性之IEEE 802.15.4通訊協定函式庫，其可以快速移植至不同硬體上，縮短產品開發時間。硬體設計為使用WISHBONE匯流排設計通訊協定硬體，其可容易地整合至嵌入式系統SOC設計中。
第二主題為IEEE 802.15.4應用於生醫監控方面，內容包含原型實作與ASIC硬體實現，結合植入式膀胱感測器與心電圖感測電路，最後實現我們提出之生醫監控雛型系統。

Due to the rapid development of semiconductor technology, the number of transistors of integrated circuits in unit area increases by double in roughly every two years. We then can add more circuits and functionality into a single chip. The size of electronic products certainly is reduced. Besides, because of the blooming popularity of wireless network standards in recently year, sensors have been wireless connected to provide more functionality and intelligence. They are, namely, wireless sensor network (WSN). Before long, the integrated circuit design will not only be emphasized on front-end circuits and hardware design, but also integration and functionality, which is so-called the system-on-chip (SOC) design.
The first topic of this thesis is the implementation of IEEE 802.15.4 network prototype and hardware design. The main purpose of prototyping is to realize the highly portable IEEE 802.15.4 protocol stack library which can be quickly transferred to different hardwares. Thus, it shortens the time to market. In ASIC hardware design, we use WISHBONE bus as the interconnection architecture which can be easily integrated into current SOC design for an embedded system.
The second topic is an application of IEEE 802.15.4 in medical monitoring, including system prototyping and ASIC hardware design, which collects the bladder pressure readings by a wireless link and ECG signals from our ASIC sensors. Finally, we realize the medical monitoring in a prototypical system.
